PreFlight_PCB

A PCB can pass every design rule check and still have problems that only show up after manufacturing. I ran into this while designing WenneBoard, my own modular mechanical keyboard. Even after checking my designs, I realized there were mistakes that traditional design rule checkers simply weren't built to catch. That's why I started building PreFlight. PreFlight is an AI-powered engineering review tool that checks existing PCB designs before they're sent to manufacturing. Instead of generating circuits, it analyzes the ones engineers have already designed. It reads KiCad projects, compares schematics against PCB layouts, runs electrical and manufacturing checks, and retrieves component datasheets. It then uses Meta Muse Spark 1.3 Contributor to investigate potential issues, cross-check evidence, and explain what could go wrong. Unlike a conventional design rule checker, PreFlight doesn't just flag violations. It helps engineers understand why an issue matters, shows supporting evidence, identifies what still needs verification, and guides them toward a fix. It also includes interactive AI chat, a guided Fix Design workflow, and experimental firmware generation. I originally built PreFlight to solve a problem I experienced myself. Now I want other hardware developers to avoid the same mistakes. The goal is simple: catch expensive PCB mistakes before they become physical boards.
